(HRW) – Incendiary weapons are among the cruelest weapons used in contemporary armed conflict. These weapons, which produce heat and fire through the chemical reaction of a flammable substance, cause excruciating burns and destroy homes and other civilian structures. They are regulated by Protocol III to the Convention on Conventional Weapons (CCW), but that instrument has loopholes that reduce its legal and normative power. CCW states parties have increasingly expressed support for revisiting and strengthening Protocol III, and they have set aside time at their annual Meeting of States Parties in November 2018 to address the topic.
Human Rights Watch and the Harvard Law School International Human Rights Clinic (IHRC) call on states to hold a robust exchange of views in November, and to dedicate additional time in 2019 for further discussions, possibly in the form of an informal meeting of experts. States should not only condemn ongoing use, but should also work toward closing Protocol III’s loopholes and building the stigma against incendiary weapons. A complete ban on incendiary weapons would have the greatest humanitarian benefits.
To bolster the case for reviewing and amending Protocol III, this paper rebuts common myths about incendiary weapons and the law that regulates them.
Myth #1: The harm caused by incendiary weapons is comparable to that of other conventional weapons.
Reality: Incendiary weapons inflict exceptionally cruel injuries, including horrific burns, which can produce immediate and long-term suffering and, in many cases, a painful death.
- Incendiary weapons can cause fourth- and fifth-degree burns that damage skin, muscles, ligaments, tendons, nerves, blood vessels, and even bones. Burns can also lead to severe infections and shock.
- Victims face an excruciating treatment process. Dressings for burns must be changed daily and dead skin removed, a painful process that has been described as being “flayed alive.”
- Incendiary weapons can also cause carbon monoxide poisoning and respiratory damage. Victims may be unable to breathe due to inflammation to the lungs or other tissues.
- Individuals who survive an initial attack often experience organ failure, lowered resistance to disease, lifelong disability, muscle weakness, and psychological trauma. Survivors sometimes find that they are also shunned due to severe scarring and disfigurement, which can drive them to withdraw from society.
- In addition to inflicting physical injury, incendiary weapons can cause socioeconomic harm and displacement because they destroy homes, hospitals, schools, farmland, and other civilian infrastructure.
Myth #2: Incendiary weapons are not a common tool in contemporary armed conflict.
Reality: Incendiary weapons have been used repeatedly in recent armed conflicts, most notably in Syria.
- Human Rights Watch documented 30 incidents involving incendiary weapons in Syria over the first seven months of 2018. The attacks, by the Syrian-Russian military alliance, took place in six governorates: Aleppo, Damascus, Damascus Countryside, Daraa, Hama, and Idlib. Syria Civil Defense reported that on March 16, 2018, an incendiary weapon attack on Kafr Batna, in Eastern Ghouta, killed at least 61 people and injured more than 200.
- From November 2012 through 2017, Human Rights Watch documented more than 90 incendiary weapons attacks by the Syrian-Russian military alliance in Syria. The total number of such attacks is likely higher because some attacks go unreported or are not recorded by visual media so cannot be investigated.
- Human Rights Watch documented use of incendiary weapons in Ukraine in July 2014, although it could not determine who fired the weapons.
- White phosphorus munitions, which have comparable effects to incendiary weapons regulated under international law, have also been used repeatedly over the past 15 years, including by US-led coalition forces against the Islamic State in Iraq and Syria in 2017; by Saudi Arabia-led coalition forces in Yemen in 2016; by Israel in Gaza in 2008-2009; by both the International Security Assistance Force and the Taliban in Afghanistan between 2005-2011; by Ethiopian forces in Somalia in 2007, and by the United States in Iraq in 2004.
Myth #3: Existing international humanitarian law is adequate to protect civilians from incendiary weapons; preventing problematic use is a matter of compliance and universalization.
Reality: While states should join and comply with the Convention on Conventional Weapons, Protocol III governing incendiary weapons has two loopholes that interfere with its ability to protect civilians.
- Article 1 of Protocol III narrowly defines an incendiary weapon as “any weapon or munition primarily designed to set fire to objects or cause burn injury to persons….” This definition excludes multipurpose munitions, notably those containing white phosphorus, which set fire and cause burns but are “primarily designed” for other uses, such as marking, obscuring, or signaling.
- Article 2’s restrictions on use arbitrarily differentiate between incendiary weapons based on their delivery system. Article 2 comprehensively prohibits the use of air-dropped incendiary weapons in concentrations of civilians, but it allows the use of ground-launched incendiary weapons in concentrations of civilians when the military target is “clearly separated from the concentration of civilians and all feasible precautions are taken” to limit the incendiary effects and minimize injury or loss of life to civilians.
- The drafters of Protocol III focused on regulating the incendiary weapons most troubling at the time of its negotiation: air-dropped weapons specifically designed to burn and set fires, notably those containing napalm. This narrow scope, however, is a legacy of the 1970s and no longer appropriate today.
Myth #4: Protocol III’s definition of incendiary weapons appropriately excludes multipurpose munitions that have only incidental incendiary effects.
Reality: By excluding multipurpose munitions, such as those containing white phosphorus, Protocol III fails to regulate munitions that cause the same harm in the same manner as those it defines as incendiary weapons.
- White phosphorus is a chemical substance that ignites when exposed to oxygen. The chemical reaction creates intense heat of about 815 degrees Celsius and produces light and a thick smoke.
- White phosphorus munitions operate in the same way as the incendiary weapons covered by Protocol III: by setting fires and causing burns “through the action of flame, heat, or combination thereof, produced by a chemical reaction of a substance delivered on the target.” As noted above, they fall outside of Protocol III’s definition of incendiary weapons because they are “primarily designed” to be obscurants.
- White phosphorus causes severe thermal and chemical burns, often down to the bone, that are slow to heal and likely to develop infections. If not all fragments of white phosphorus are removed, they can exacerbate wounds after treatment and reignite when exposed to oxygen. White phosphorus burns on only 10 percent of the body are often fatal.
- In 2008-2009, for example, Israel’s use of white phosphorus munitions in Gaza killed at least 12 civilians and left dozens suffering from deep burns and respiratory damage.
- The use of white phosphorus munitions between 2005 and 2011 in Afghanistan also severely burned civilians, including an eight-year-old girl, who went through fifteen surgeries due to the extensive burns on her face, head, neck, and arms. Her recovery period took a number of months because whenever doctors tried to “scrape the dead tissue, flames leapt out.” While she and five other family members ultimately survived the attack, two of her sisters died.
Myth #5: Armed forces need white phosphorus munitions because of their effectiveness as obscurants.
Reality: The humanitarian harm caused by white phosphorus munitions outweighs their potential usefulness on the battlefield, and less dangerous alternatives exist.
- Protocol III should regulate white phosphorus munitions, despite claims about their military utility, because of the cruel and indiscriminate harm they cause. In the past, weapons that inflict unacceptable harm, such as antipersonnel landmines and cluster munitions, have been banned or regulated regardless of purported military benefits.
- In addition, there are alternative obscurants to white phosphorus munitions, such as 155mm smoke projectiles, which produce comparable visual screening properties without destructive incendiary effects.
- Some states have already turned to such alternatives in response to public pressure. While Israel used white phosphorus munitions in Gaza in 2008-2009, it began developing alternative smoke shells after it was widely condemned for the harm its munitions caused. There have been no reports of Israeli use of white phosphorus in Gaza since 2009, although it has conducted further military operations there.
Myth #6: Protocol III’s distinction between air-dropped and ground-launched incendiary weapons reflects meaningful differences based on the types of delivery mechanism and frequency of use.
Reality: The distinction between air-dropped and ground-launched incendiary weapons is arbitrary because they cause the same type and magnitude of harm and have both been used in recent conflicts.
- The delivery system of an incendiary weapon is irrelevant because the nature and extent of harm is the same. An individual will suffer cruel injury regardless of how the incendiary warhead reached them. Protocol III itself states that all incendiary weapons “set fire to objects or … cause burn injury to persons.”
- Both air-dropped and ground-launched incendiary weapons have been used in populated areas in recent conflicts. In 2017, most of the 22 incendiary weapons attacks that Human Rights Watch documented in Syria involved air-dropped models. In 2018, Human Rights Watch documented that the Syrian-Russian military alliance used ground-launched incendiary Grad rockets in at least 20 instances and air-dropped incendiary weapons in at least 10 instances.
- Ground-launched incendiary weapons, in particular 9M22S Grad rockets, were also used in July-August 2014 in at least two towns in Ukraine, Ilovaisk and Luhansk. They burned several homes and endangered civilians.
- Because they generally lack aircraft to drop incendiary weapons, non-state armed groups are more likely to have access to ground-launched models. For example, the US military reported 11 cases from 2007-2009 in which insurgents used white phosphorus delivered by rockets or mortars in Afghanistan.
Myth #7: Amending Protocol III would be complicated and time consuming.
Reality: Strengthening Protocol III, which requires only small changes to the text, would be legally and procedurally straightforward.
- Expanding Article 1 to cover multipurpose munitions with incidental incendiary effects would simply require shifting from a design-based to an effects-based definition. The language could be changed to “any weapon or munition that has the effect of setting fire to objects or causing burn injury to persons….”
- Precedent for adopting an effects-based weapons definition exists in CCW Protocol I on Non-Detectable Fragments, Additional Protocol I to the Geneva Conventions, and the Nuclear Weapons Advisory Opinion issued by the International Court of Justice. Each of these documents looks to the effects of particular types of weapons in order to determine their legality.
- Strengthening restrictions on use would simply require eliminating the distinction in Article 2 between delivery systems. Article 2(2) could be amended to remove “air-delivered,” so that it prohibits making “any military objective located within a concentration of civilians the object of attack by incendiary weapons.” Article 2(3) could then be deleted.
- Treaties regulating conventional weapons generally do not distinguish based upon delivery system. For example, Amended Protocol II to the CCW, which covers mines, booby-traps, and other devices, defines a “remotely-delivered mine” as a mine “delivered by artillery, missile, rocket, mortar, or similar means, or dropped from an aircraft.”
- The process to amend Protocol III could be similarly straightforward and completed in a timely manner. States should set aside time to review Protocol III in 2019 and then agree to a negotiating mandate with the goal of strengthening the protocol the following year.
Myth #8: States are resistant to amending Protocol III.
Reality: Growing state support for strengthening the law and condemnation of recent use demonstrates the time is ripe for CCW states parties to revisit Protocol III.
- Since 2010, at least 35 states, along with other international actors including the International Committee of the Red Cross (ICRC) and the UN secretary-general, have publicly recognized the problems of incendiary weapons.
- In November 2017, CCW states parties engaged in particularly robust discussions when the topic became a separate agenda item at their annual meeting. Almost all of the 26 states that spoke expressed concerns about incendiary weapons, and the majority recommended CCW states parties take some action in response.
- At least nine states supported amending Protocol III. For example, Costa Rica described ongoing use of incendiary weapons as an “alert” to evaluate and expand the scope of Protocol III. Austria said it “continues to see value in strengthening Protocol III,” while Chile promised to work with “like-minded States and civil society in order to bring about an effective prohibition of this type of weapon and to strengthen Protocol III.”
- At least 13 states called for further discussions on Protocol III. For example, the Holy See urged “[a]n honest technical and legal review of the provisions.”Croatia stated, “[T]he time is right to discuss the relevance of standards set by Protocol III,” while the Philippines agreed that “review and reflection is timely and consistent with the objective of keeping the convention and its protocols relevant.”[35
- Switzerland proposed an informal meeting of experts regarding Protocol III. While this proposal was ultimately blocked by a few states parties, at least five states expressly supported it.
- At least 17 states plus the European Union condemned or expressed concerns about reports of recent and ongoing use of incendiary weapons in concentrations of civilians at the CCW’s annual meeting in 2017. For example, Zambia “condemn[ed] in the strongest terms the use of incendiary weapons in populated areas regardless of the method of deployment.” The United States said it was “deeply concerned over the continued reports of air-delivered incendiary weapons being used in areas near civilians,” while Ireland described such reports as “disturbing.”
- Final reports from CCW annual meetings, which are adopted by consensus, have noted concerns regarding incendiary weapons with increasing urgency since 2011  At the end of the CCW’s 2017 Meeting of States Parties, the final report “condemned any use of incendiary weapons against civilians or civilian objects, and any other use incompatible with the relevant rules of international humanitarian law, including the provisions of Protocol III where applicable.”
Myth #9: CCW states parties should not make Protocol III a priority for discussion because attention would be better spent on tackling new issues than revisiting agreed-on protocols.
Reality: CCW states parties should prioritize revisiting and strengthening Protocol III because the convention is intended to be a living document and states parties have not revisited Protocol III since it was adopted in 1980.
- At the 2017 Meeting of States Parties, several CCW states parties remarked that a review of Protocol III was long overdue. While, in the words of Costa Rica, the CCW was designed to be “a convention that is dynamic and flexible,” Protocol III has remained static for almost four decades.
- States parties have, by contrast, expanded and strengthened other elements of the convention and its three original protocols several times since adoption. States parties have amended Protocol II, added two new protocols, and expanded the scope of the convention to encompass non-international armed conflicts.
- Work on incendiary weapons need not distract from progress on lethal autonomous weapons systems because states parties to the CCW have demonstrated their ability to work on multiple issues at the same time. For example, while states parties were negotiating Protocol IV on blinding laser weapons in 1995, they were also amending Protocol II. In 2003, states parties both adopted Protocol V on explosive remnants of war and agreed to a political commitment on mines other than antipersonnel mines.
- The evidence of ongoing use of incendiary weapons and growing calls for a response underscore the urgency of revisiting Protocol III.
Myth #10: Amending Protocol III will not have a significant impact.
Reality: Closing the loopholes in Protocol III will better protect civilians by more strictly regulating states parties’ use of incendiary weapons and by creating a more powerful norm against their use.
- A stronger protocol would bind states parties, meaning they could not lawfully engage in use that falls into the current loopholes. Eliminating ambiguity in Protocol III would also facilitate enforcement because with clearer rules, breaches are easier to recognize and condemn.
- Strengthening Protocol III could also influence the conduct of actors not bound by its provisions by increasing the stigma against incendiary weapons. Stigmatization has already contributed to changes in domestic policies. For example, growing opposition to incendiary weapons, at the international and national levels, helped pressure Israel, which is not party to Protocol III, to alter its policies on white phosphorus in 2013 in order to dramatically restrict use.
- Stigmatization can also influence the conduct of non-state armed groups, especially those that seek to be viewed as responsible actors.
